Replace YAML parsers

[suzuki-shunsuke]

There are three packages.

• https://pkg.go.dev/github.com/goccy/go-yaml
• https://pkg.go.dev/gopkg.in/yaml.v2
• https://pkg.go.dev/gopkg.in/yaml.v3

We couldn't use gopkg.in/yaml.v3 because gopkg.in/yaml.v3 didn't have Git tags.
But currently gopkg.in/yaml.v3 has tags, so we can use gopkg.in/yaml.v3 safely.

Replace goccy/go-yaml to gopkg.in/yaml.v3 partially

We use goccy/go-yaml for the following purposes.

1. Patch YAML: gopkg.in/yaml.v3 also supports this feature
2. IndentSequence: Only goccy/go-yaml supports this feature

Regarding IndentSequence, we still use goccy/go-yaml because only goccy/go-yaml supports this feature.

But regarding patching, maybe we can use gopkg.in/yaml.v3 instead of goccy/go-yaml.
I haven't patch YAML using gopkg.in/yaml.v3, so I have to verify it.

goccy/go-yaml has some issues.

1. aqua g -i ignores the indent of registries when packages: is empty #585
2. aqua g -i removes new lines #584
3. Exec performance regression #582

Replace gopkg.in/yaml.v2 to gopkg.in/yaml.v3

We use gopkg.in/yaml.v2 instead of gopkg.in/yaml.v3 because gopkg.in/yaml.v3 couldn't parse YAML which has duplicated keys.
aqua should allow invalid YAML as much as possible, so we couldn't use gopkg.in/yaml.v3.

But I reconsider that we can use gopkg.in/yaml.v3 mainly and use gopkg.in/yaml.v2 only when gopkg.in/yaml.v3 can't parse YAML.

How do we keep indent by yaml.v3?

https://go.dev/play/p/TubU0SPmY69

package main

import (
	"log"
	"os"

	"gopkg.in/yaml.v3"
)

func main() {
	if err := core(); err != nil {
		log.Fatal(err)
	}
}

const data = `
---
packages:
- name: cli/[email protected]
`

func core() error {
	var cfg yaml.Node
	if err := yaml.Unmarshal([]byte(data), &cfg); err != nil {
		return err
	}
	if err := yaml.NewEncoder(os.Stdout).Encode(&cfg); err != nil {
		return err
	}
	return nil
}

Result: Indent was changed.

I found issues.

• v3: preserve comments lines and indents after unmarshal -> marshal go-yaml/yaml#709
• Track indentation in yaml.Node go-yaml/yaml#899
